Causes of a Blank Login Screen in Okta

This document outlines some causes of the Okta Sign In Widget (SIW) displaying a blank login screen.

• Okta Identity Engine (OIE)
  
• Okta Sign-In Widget (SIW)
• Login Screen

There are several reasons users see a blank sign-in page.  Below are some examples:

• VPN or communication issues: GlobalProtect VPN Okta Login Shows Blank Window Until Maximized.
• Limitations of WebView2 code: Remote Help Application Shows a Blank Okta Login Page.
• Unsupported Platforms: 
  • Okta Verify Does Not Work During Out-of-Box Experience in Windows Autopilot.
  • Upgrade the Sign-In Widget.

To troubleshoot this issue:

• Review the Sign-In Widget Fundamentals section of the development guide when embedding authentication in code.
• Ensure that no communication or firewall issues exist between the browser, the local machine, and Okta by reviewing IP Address Allow Listing and Okta Verify Fails to Prompt for Authentication on Corporate Networks.
• Verify that no time skew exists between the machine hosting the embedded code and the Okta Amazon Web Services (AWS) server.
• Confirm that the browsers and platforms are supported by reviewing Supported Platforms, Browsers, and Operating Systems.
